and no amount of  pleading to staff will get ANYONE back in.. seen some try and failed. 

no worries dear Maher..  the site settings automatically prevents anyone from re-entering a vote chess game once they leave the game or leave the group.. not everyone knows this and find out the hard way!

..thanks dear Barbara for informing me about that .. i will tell them ..

Just remind them though Uncle Maher, in your newsposts that if they are in any vote chess games then once they leave a group they cannot return to that vote chess game under any circumstances.
